Liquid Chromatography - Aqueous Solvent Mixtures 3

Katz et al. measured the distribution coefficient of benzene between n-hexadecane and some methanol/water mixtures. Using the data from figure 47, they plotted the distribution coefficient of benzene against the volume fraction of methanol unassociated with water. The results they obtained are shown in figure 48.
